# GPS Speedometer vs Authenticator

The clearest difference is ads: Authenticator at none against GPS Speedometer's shown. Authenticator also leads on rating (5.0 vs 4.6). GPS Speedometer's advantage is ratings volume (33 vs 3) and device support (3 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. GPS Speedometer sells 4 in-app purchases, starting at $4.99 per 7 days and Authenticator sells 3 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Authenticator holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: GPS Speedometer has 33 ratings behind it against 3, so its average is the more settled of the two.

GPS Speedometer ships an update every 3 weeks, Authenticator every 5 weeks. Both last shipped on October 30, 2026.
